Introducing Yonkoma by Mark Steere
Thank you for adding Yonkoma to PlayStrategy. I realize you're not trying to explain the entire rule set in the intro, but I would add that you can either move a checker closer to the enemy checkers, or maintain that distance and move one of your checkers farther from the other one.
The second part of that prevents deadlocks. Distances are king move distances.
